The phase and composition of Liupanshui gangue are tested by XRD and XRF respectively. The activation properties of coal gangue as cement admixture at different calcination temperatures are investigated. The results show that: Liupanshui coal gangue as a binder to join the cement cementing material, its optimum calcination temperature is 600°C and the best dosage of coal gangue calcined is 30%. When the coal gangue activation temperature at 600 °C, the incorporation amount is 30%, the 28d compressive strength of cement mortar is 59.2MPa, and the maximum flexural strength is 10MPa.
